Nexxim®, Ansoft's circuit simulation and analysis software, delivers high-performance, high-capacity, transistor-level simulation for complex RF/analog/mixed-signal IC design and verification.

The software provides the transistor-level accuracy required to simulate sensitive analog and wireless front-end circuits and the robustness and capacity to address the diversity and complexity of modern mixed-signal integrated circuit designs.

Nexxim dynamically links to Ansoft's industry-leading electromagnetic field solvers, HFSS™, SIwave™, and Q3D Extractor® through Ansoft Designer®. Therefore, engineers can achieve first-pass system success by precisely modeling and integrating high-frequency effects in their circuit designs, gaining insight into signal integrity and power integrity issues.

New in Nexxim v4

  • VerifEye™, a new methodology for eye analysis of serial links using statistical methods that maintains accuracy while offering major reductions in run time compared to conventional transient methods. These statistical transient analysis tools represent the most practicable means to test for the low bit-error rates needed by today's multi-Gb/s channel designers.
  • QuickEye™, a new Ansoft-only fast eye diagram analysis method that allows input of very long, user-defined bitstreams. This analysis allows engineers to identify specific bit sequences that cause bit errors.
  • Mixed system-level behavioral simulation with transistor-level transient simulation. This hybrid integration enables designers to simulate a complete system consisting of various levels of abstraction much more quickly than in simulators that operate at only the transistor level.
  • C model editing wizard
  • Ability to compute the reciprocal response of subcircuits, Nports and Field Solver elements to de-embed the effects of test fixtures.
  • Transient noise analysis
  • Transmission line tool

Nexxim® Software combines with Ansoft Designer™ Software, HFSS™ Software, and Q3D Extractor™ Software, to provide the most complete RF/AMS circuit-design software solution commercially available.
